Indian authorities have arrested Aleksej Besciokov, an administrator of the Russian cryptocurrency exchange Garantex, at the request of the US.

Besciokov, a Russian resident and Lithuanian national, was taken into custody in Kerala on charges of money laundering and violating sanctions. The Central Bureau of Investigation (CBI) said he was planning to flee India, and Washington is expected to seek his extradition.

The arrest follows a joint operation by the US, Germany, and Finland to dismantle Garantex's online infrastructure.

The exchange, under US sanctions since 2022, has processed at least$96 billion in cryptocurrency transactions since 2019. The US Justice Department recently charged two administrators, including Besciokov, with operating an unlicensed money-transmitting business.

Experts warn that sanctioned exchanges often attempt to bypass restrictions by setting up new entities. Blockchain research firm TRM Labs called the Garantex takedown a significant step in combating illicit finance but emphasised the need for continued vigilance against evasion tactics.
